What it takes to be a London Cabbie

The Knowledge of London:

To become a London black cab driver, one must pass "The Knowledge of London," a test known to be one of the most challenging in the world, requiring extensive knowledge of over 25,000 streets and somewhere in the region of about 100,000 landmarks. Passing this test is an incredible accomplishment that's equivalent to earning a four-year degree from the University of London. Students are required to have an intimate familiarity within a six-mile radius of Charing Cross! (Trafalgar Square). Incidentally, the area where a taxi is legally required to accept a fare without refusal is within a twelve-mile radius, or if the journey will take longer than an hour.

The origins of the Knowledge of London, remain uncertain, but according to popular belief, it was introduced in 1865. Although there are no records to corroborate this, records do show, however, that the Knowledge of London was in place in 1884. It is suggested that the knowledge was derived from the Great Exhibition of 1851 held in Hyde Park. During the event, numerous visitors voiced their complaints to the local authorities about the cabmen who were not familiar with the city's routes and streets, this led to the creation of the “Knowledge of London”.

Knowledge of London candidates must pass a rigorous series of oral exams called "Appearances". During these Appearances, the student must demonstrate a comprehensive knowledge of the city's streets and layout. Specifically, they must be able to recite the most direct route between any two points selected by the examiner. The exam covers points of interest ranging from well-known landmarks to obscure back alleys. This ensures that licensed taxi drivers in London have a deep understanding of the city's geography and can navigate passengers to their destinations in the most direct and efficient manner possible.

As mentioned earlier, aspiring taxi drivers in London must have a comprehensive knowledge of the city's noteworthy establishments and public facilities. This includes committing to memory the locations of hotels, clubs, cinemas, and theatres, as well as museums, art galleries, and historical buildings. Furthermore, they must be familiar with train stations, ambulance stations, fire stations, bus garages, housing estates, parks, and open spaces, as well as government buildings, financial and commercial structures, embassies, town halls, registry offices, hospitals, prisons, police stations, palaces, and places of worship. They should also know football grounds, airline offices, schools, academies, colleges, and universities, as well as civil, criminal, and coroner's courts. In short, they should be familiar with every nook and cranny of the city. Once they have achieved and satisfied the examiners with the required level of proficiency, they can then proudly join London's iconic Licensed Taxi Trade.

Did you know?

A study backed by the Welcome Trust, led by neuroscientist Dr. Eleanor Maguire in 2000, revealed some exciting insights. It showed that individuals who spent around two years learning the intricate ‘Knowledge of London’ exhibited a larger right hippocampus compared to a control group (placebo group). Moreover, it turned out that the longer these individuals worked as black cab drivers, the more significant the growth in their hippocampus became. impressive, right?

Doing “The knowledge”

The Green Badge.

So, as you can see, becoming a licensed taxi driver in London is quite an accomplishment. It requires a significant investment of time and effort, typically taking between two and a half to five years to learn and pass the rigorous written and oral exams of the 'All London Knowledge' (also known as the Green Badge). However, it's worth the effort since successful candidates are awarded the coveted badge, which allows them to legally operate (ply for hire) as taxi drivers on the streets of London.

The most efficient and widely adopted method of doing the Knowledge is by cruising the streets on a moped with a clipboard securely attached to the handlebars to hold your Blue Book runs, maps, and notes. Of course, the choice is entirely yours - some individuals prefer to use their cars, cycle, and even walk!

The Yellow Badge:

Suburban drivers.

Drivers with a Yellow Badge licence undergo a similar process as those with a Green Badge, but they are restricted to accepting street hails within their designated suburban area. They still have to acquire a comprehensive understanding of the streets and notable locations but just for their specific sector. The process typically takes about 18 months to complete due to the size of the designated area.
It's important to note that yellow badge drivers can only pick up passengers outside of their sector if they have already arranged with their passengers to do so once dropping them off. However, the introduction of ride-hailing apps has created some loopholes in the system that can make things a bit unclear.
Nine suburban sectors cover the north, east, south and west areas in the Greater London region.

The Blue Book:

The Blue Book is the basis of “The knowledge”, It contains a list of the 320 core routes, running up, down, through, and across the city that the student has to learn, and build their knowledge of the city from thereon. The book contains only the start and the end locations, ie, Run No.1,

Manor House to Gibson Square. It’s up to the student to work out the actual route, although nowadays you can purchase the complete routes/runs from any of the authorised Knowledge schools that are located in and around London.

Knowledge boys and girls will start their runs by taking in each street name and picking up relevant points of interest along the way.
This is a proven method of learning as it ensures the examiners that the student has actually visited these locations and not just memorised the runs.

To enhance their knowledge even further, students do Cross Section runs. This helps immensely to connect the roads, and for it all to fall into place, like placing the last piece of a puzzle.

Appearances: ( one-on-one exams )

Before diving into roughly a year-long series of Appearances, students must pass a map test—a multiple-choice challenge proving they're ready for the one-on-one oral examinations. Following the initial Appearance, which ordinarily spans around 20 minutes, the student may be requested to attend another session after 56 days, depending on their level of success. Appearances are evaluated on a points system ranging from A to D, with a higher score corresponding to A. Specifically, a score of 0 - 23 corresponds to D, 24 - 32 to C, 32 - 36 to B, and 37 - 40 to A.

The journey continues as students accumulate points, triggering a reduction in the time between Appearances—from 56 days to 28 days and finally down to 21 days. On average, students participate in around 5 sessions per consecutive group, totaling between 20 and 25 Appearances, but this varies based on individual progress, this usually happens at the early stages when they could spend longer on their 56 and 28-day Appearances. Each question starts with 10 points. Depending on how well they recite that run, for example; Make a misstep—like an illegal turn, an unexpected detour, or confusion about roads—points will be deducted.

Here's the fine print: Before embarking on this amazing educational journey, all students undergo an extensive criminal history check. Once you're in, the only way to fail is by committing a serious crime whilst on ‘The Knowledge’—a bit like staying on the right side of the law in the game of life.

My experience:

Embarking on the saga of Appearances, each student's tale is as unique as a fingerprint. Some breeze through it effortlessly, while others, like myself, found it to be a heart-pounding, nerve-wracking experience—one that forever lingers in memory.

On the eve of an Appearance, I opted for a different ritual. Instead of last-minute callovers, I aimed for relaxation amidst the nerves. My friends had their strategies, calling over the night before or even in the morning. It's a personal journey, and comfort is key. Before bedtime, I'd ensure my suit, shirt, and tie were laid out meticulously, and my shoes shone brightly. The importance of impeccable attire in the character assessment cannot be overstated—it's a silent, but very important part of the journey to becoming a London cabbie.
Dawn broke with an extra-early rise, and a leisurely 45-minute bath to mentally brace for the dreaded Appearance. Living near Golders Green, I'd drive to my in-laws' in Camden, then embark on a 25/30-minute walk to the Public Carriage Office in Penton Street—the arena for Knowledge of London Appearances. Each step was a moment to ease the mind.

The nervousness? A testament to the importance of the journey. Life was on the brink of positive change, and the last thing you'd want is to let yourself down or your family—the very reason you embark on this quest. That jittery energy becomes the fuel propelling you towards the dream of donning the title of a Licensed London Taxi Driver.

Becoming a London cabbie transformed more than just my job—it moulded confidence, discipline, and the art of engaging with people positively and professionally. If I could alter any part of the K.O.L. process, I'd rewind to 1990/1. Back then, examiners instilled a fear that bred respect, an appreciation for the gravity of the job, and an understanding of how easily a licence could be revoked.

London taxis and their drivers are revered globally, standing as the paragon of excellence and an unattainable gold standard. From the first run you do on your moped to that monumental first fare, the journey is etched in high standards, creating a legacy that remains unchallenged.
